Ms ATTORNEY Patented Jan. 26, 1937 UNITED STAYS PATENT OFFICE 8 Claims.

This invention relates to the construction of panels or panes being sub-divided into a plurality of small sections supported at their joints by cames interconnected to form a unit in a frame,

such as would be set and secured in the usual way in the muntins of a window or other frames or structural places.

In particular, among the aims of the invention are the provision of a structure which provides simplicity and economy in assembly of the plurality of small sections of any sheet material which in the case of windows are usually of glass, the ready replacement of individual pieces, and particularly fireproofness when used in a window, greater strength than in the practices heretofore employed, and other advantages that may appear from the more detailed construction hereinafter set forth.

In the preferred form in the practice of my invention, stiff metal cames, as distinguished from the pliable lead heretofore used, constitute the holding members for the plurality of small sectional sheets of material. These stiff metal cames constitute a lock joint metallic glazing of a panel, in which the intersections of the cames are so fashioned as to provide continuous cames extending from side-to-side or end-to-end of the frame, thereby providing lateral strength against the panel or pane and still assuring simplicity of assembly as Well as the advantages of replacement, and fireproofness. While such panels or panes heretofore have been built up and assembled with metal cames with break-joints, and as such metal cames have required soldering at the joints or at the junctions of the individual came members, such structures are subject to practical ruin in the case of fire and a sufficient heat that causes the solder to run, with the attendant collapse of the assembled parts. The utility of this invention is evident when considering that the present invention permits of the use of stiff metal cames such as aluminum, copper or bronze, and that each came member extends from the substantial bordering frame member from side-toside or end-to-end of the panel, thereby resisting strains and resisting any heat that would ruin a soldered came assembly. 'It permits the use of aluminum for lightness. In the case of bronze for durability, it permits the lightest possible structure, thereby saving in cost, still preserving durability and appearance, and in the case of bronze very thin sheet may be drawn into the came formation with spacing left in the leaves of the came so that stiff rigid steel strips may be put into such spaces, or sockets in the leaves of the came to add to the desired strength, while having the exposed surfaces of bronze or other relatively expensive metal for durability and appearance.

A feature of the construction may involve the two-elevation arrangement of intersecting cames, that is at the joints the cames in one direction have their leaves overlapping or at a greater elevation from the surface of the section of sheet material,-than the leaves on the cames extending in the cross direction, but it also permits of the depression of the leaves on the higher elevated or slightly deeper section cames between the intersections, so that such leaves may be depressed to more closely contact with the adjacent edges of the sheet sections. In any event, the series of cames in one direction having the lesser sectional depth provide the desired groove or pocket to snugly engage the edge of the thin sheet pieces and hold them with all the required I rigidity in the assembled structure. For the slight inequality of engagement of leaves of some of the cames with the glass or other sheet surface, suitable material such as putty or the like, assures the air-tightness of the joints, while on the other sides of the glass or other sheet pieces the close engagement with the stiff cames provides for rigidity of theentire panel or pane.

While in the preferred form each panel or pane has a substantial border frame, and the traversing 0 members have their ends rigidly secured where they join the bordering frame by a rivet or the like, the frames may be made up without rigid connection of the came members to the border, but by assembling the entire came and glass structure progressively and then adjusting the frame border members and riveting the outer frame members at their intersections or at the corners of the pane. This is shown as to the set of transverse members as herewith illustrated, being riveted, whereas the vertical members are shown without any riveted or positive connection, and in the practice of the invention both sets of came members may be assembled in either one way or the other.

In a modified form the cames extending in one direction may be continuous, forming stiff strainresisting members extending from one frame member to the other, while the cames in the transverse direction may be in sections. form each transverse section of came may abut the heart of the through stiff cames and be clipped or pinned to the heart of the came extending from border-to-border of the frame. In such form the short sections of transverse came In such may form a slotted heart through which a double strip passes forming a reinforcement with the ends of the strip extending beyond the came proper and through a positioning slot on the through cames where the ends of the reinforcement are turned over, so that they hold the short came section rigidly positioned and rigidly assembled with the through cames.

In another form of the invention, one set of cames, that is the cames going generally in one direction, are provided with reinforcing strips in sockets in the leaves, and at the intersection with the transverse cames the web is cut away letting through the transverse came which is provided with a reinforcing strip in the heart,-thus insuring continuous rigidity and'strength by the reinforcing strips or by the.v cames, with the strength-aiding member, namely, the reinforcing strip of each set of cames being continuous past the intersection or joint. In such form the cames may have the same dimensional section or depth, and at the intersection or joint the came passing through is assembledby cutting the web of the other came and spreading the leaves slightly at the joint,so that except at the joint the came members in both directions have the same size grooves between their'leaves for the accommodation of the edges of the small sectional sheet pieces.

Various modifications of the preferred and modified forms will be evident from the more detailed description hereinafter set forth. It will be understood that the came structure of the panel or frame is herein essentially involved, irrespective of the many variations of the small sectional pieces supported thereby, and while transparent or opaque glass may be thin sectional sheet material, the structure is equally applicable for the support of other sheet material in small sections such as tiling, wood, celluloid, or otherwise, in connection with which the inherent advantages of the structural coordination apply.

The specific embodiment of my invention will be described with respect to window panels with their plurality of sheet glass sections, while in no wise limiting what I claim as myinvention to such particular'embodiment.

Particular forms of the invention are shown in the accompanying'drawing in which:

Fig. I is an elevation of a panel or pane containing one form of the'metallic glazing.

Fig. II is a section on the line 2-2 of Fig. I, showing one form of the construction of the stiff cames at one intersection or joint.

- Fig. 11a is a perspective showing another form of intersection or joint.

Fig. III is a cross-section on line 3-3 of Fig. I.

Fig. IIIa is a perspective, fragmentary View, of a cross-section of the border member of the frame.

Fig. III!) is a perspective, fragmentary, showing a section of a modified form of border member of the frame.

Fig. IV is a cross-sectional fragmentary view showing border member and intersection of cames.

As shown in Fig. I the stiff metallic cames A, A, extend completely across the frame or glazed panel with transverse stiff metallic cames B, B, also extend transversely, and having their came leaves under the came leaves of A and A, that is at the joint the surfaces of thecames are at different elevation, one above the other on both faces of the panel. The cames A,'A engage at the ends the frame border members D, D, and the cames B, B engage theframe members D, D,

and are secured thereto at d by a rivet or clip or screw. The stiff came members hold the subdivided glasses or glass sections E by the came leaves, so that the entire structure when assembled is firm and solid, all slight crevices between the glass members being filled in the usual manner by putty, or some other weather-proof material.

In Fig. II the came member A has its web a cut away forming the hole F, through which came member B passes with the leaves of came A spread apart slightly to permit came B to pass through, and when in position to be held tight by the stiff came structure of member A. The incision or opening F may be made by punching the web of came member A to form a hole shaped like and slightly larger than the section of came B, as shown dotted on one side in Fig .11 or it may be substantially larger in order to allow slight relative movement of the two cames, in order to adjust themselves to accommodate any slight inequalities of the glass sections assembled with these cames in the glazing operation, or expansion in case of fire.

In the case of Fig. 11a, the came G has reinforcing strips 9 passing through the leaves, and came H has a reinforcing strip h passing through the heart of the came. In this form the heart of came G is cut away without severing the reinforcing strips g, and therefore leaves the major strength of the came intact. In particular embodiments of the construction, the major strength of came H may be preserved by carrying the reinforcing h through the web or heart of came G, thereby minimizing the cut in the heart of came G.

In Fig. III, border D is shown as having rivets passing through it and passing through a filler or spacer d, and also passing through the leaves of came B which at its end has its heart cut away to accommodate the filler or spacer (2. As illustrated in this figure the came A being of deeper section atthe joint C has its leaves spaced slightly away from the surface of the edge of the glass section E, and filling material such as putty or suitable cement J Waterproofs the crack.

Fig. IIIa shows a border member D in box form adapted to receive the edge of the glass E, and with inturned edges (1 adapted to engage the glass surface, but with incisions (1 provided for the accommodation of came members such as B In Fig. III?) a frame member is shown D which has a recess (1 on its inner side adapted to receive the edge of the glass.

In Fig. IV, the came A spans the came B shown in section, with its leaves, but between the border and the came intersection C the leaves of came A are pressed in or constricted so as to more closely approach and engage the surface of the glass at its edge, thereby adding to the stifiness of the entire glazed .panel and minimizing the space required for waterproofing by putty or the like. In this form a came B may be embodied adjacent the margin of the panel in order to accommodate the edge of the glasses, while the intersecting came A has its heart cut out to an extent permitting the leaves to project laterally over a filler or spacer K, to which the leaves are riveted. This form may be used when no solid border frame member is required, or for particular accommodation of other features of construction.

In the case of excessive temperature change, as in the case of fire, a portion of the panel or the entire window will be subject to expansion by the heat, and this may be uneven, so thata local strain may cause cracking of glass, which may be avoided by features of this invention. For such purpose where one came passes through the heart of another at a joint, the hole in the heart is made larger than the section of the traversing came, in order to permit automatic adjustment at the joint to relieve of any strain due to unequal relative expansion of the parts of the glazed panel, and thereby minimize the chance of breakage.

The use of this invention makes possible came glazing without soldered joints, and practical as to economy, durability and in all respects it solves the problem of using aluminum for cames in glazing.

It will thus be seen in the various embodiments of this invention a glazed panel structure is provided, which permits of simple assembly with the came members engaging the glass pieces to secure them, while the cames may extend continuous in both or in one direction, in any event from side-to-side of the glazed panel, thereby providing rigidity throughout the pane. As shown, the cross-sectional structure of each came is preferably drawn or extruded, and sheet metal drawn to the form admirably provides for such came structures applicable to the invention, in zinc or copper, aluminum or bronze, and the like, all forming a stiff and wind-resisting strength from lateral pressure on the pane or panel of the window. The came structures may be wholly of the stifi metal, or may be formed of stiff metal or stiifeners, with a lead coating for the benefits of weatherproof sealing on the glass surface, and also protection by lead portions of the came structure over the other metal.

While shown in Fig. I with the came members in one direction being let into the border or frame member without rigid attachment, it will be understood that upon progressive assembly of the cames with the glasses the entire panel structure is complete when frame or border members are attached, and in many cases no additional rigid clipping or clamping or bolting of the cames to the frame members at their junction are required, beyond the firm connection of the several frame or border members at the corners, or at their intersections.

The invention provides for quick assembly and secure holding of the assembled structure with economy of construction, simplicity, and facility for repairs in case of breakage of individual sectional sheet pieces. The rivets or bolts or screws, or the like, securing the corners of the frame members are preferably separable for the purposes of repair or replacement of the entire panel or pane. The panel or pane as a whole is set into the muntin, or frame or into the sash, and secured in any usual manner. It will be seen that the assembled structure provides for rigidity against lateral pressure on a panel, and

against warping, irrespective of the small sec-' tional sheet pieces, which therefore may be of any material. Small sheet sections of material which heretofore have been used in large pieces and subject to warping, or otherwise, lack durability when used architecturally in large areas, lend themselves admirably to application in a plurality of small sections, readily assembled and admirably supported by the structure involved in this invention. It will also be evident that the assembly of small sections of any material whether transparent or opaque provides for covering the adjacent edges of the small sections completely and effectively, which if otherwise assembled would require expensive and some times difficult work in joining of the edges and preservation of the joints.

While various modifications may be made in many features of the construction or material herein described without departing from the invention, what I claim and desire to secure by Letters Patent is:

1.
